# std::execution::just_stopped

From cppreference.com
< cpp‎ | execution

Defined in header `<execution>` |  |
inline constexpr just_stopped_t just_stopped{}; struct just_stopped_t { /*unspecified*/ }; |  | (since C++26) (customization point object)
Call signature |  |
execution::sender auto just_stopped(); |  | (since C++26)

A sender factory that returns a sender which completes immediately by calling the receiver’s `set_stopped()`.

The expression just_stopped() is expression-equivalent to /*make-sender*/(just_stopped)

### Customization point objects

The name `execution::just_stopped` denotes a customization point object, which is a const function object of a literal `semiregular` class type. The cv-unqualified version of its type is a tag type denoted as `execution::just_stopped_t`.

All instances of `execution::just_stopped_t` are equal. The effects of invoking different instances of type `execution::just_stopped_t` on the same arguments are equivalent, regardless of whether the expression denoting the instance is an lvalue or rvalue, and is const-qualified or not (however, a volatile-qualified instance is not required to be invocable). Thus, `execution::just_stopped` can be copied freely and its copies can be used interchangeably.

Given a set of types `Args...`, if std::declval<Args>()... meet the requirements for arguments to `execution::just_stopped` above, `execution::just_stopped_t` models

- std::invocable<execution::just_stopped_t, Args...>,
- std::invocable<const execution::just_stopped_t, Args...>,
- std::invocable<execution::just_stopped_t&, Args...>, and
- std::invocable<const execution::just_stopped_t&, Args...>.

Otherwise, no function call operator of `execution::just_stopped_t` participates in overload resolution.
